ProtoForge Sourcing
ProtoForge Sourcing
We act as your buy-side agent for build-to-print machined and injection-molded parts. Leveraging factory clusters in Suzhou/Kunshan/Changzhou, Ningbo/Taizhou, and Dongguan/Zhongshan, we deliver 48h transparent quotes, rapid prototyping (3–7 days machining; 10–20 days T0/T1 mold trials), and dependable mass production (10–20 days machining; 15–30 days molding). We cover CNC, turn-mill, post-machining for die castings, and in-house mold design/build (tool life 100k–300k shots) across AL6061/6063, SS304/316, Q235/45#, ABS/PP/PC/PA+GF. You get ISO 9001 shops (with partial IATF 16949/ISO 13485), AQL-based QC, material spectrometer reports, RoHS/REACH declarations, and clear EXW/FOB terms with DDP trials for samples/small lots.

6) Payment & Fees
- T/T: 30–40% deposit; balance before shipment.
- Tooling milestones: 40/30/30 (kickoff / T1 approval / pre-ship).
- L/C: Available for large orders.
- Sample fees: Quoted per SKU; can be offset against first mass-production order.
7) Communication & PM
- Engineer-led English/Chinese communication.
- SLA: Drawing/DfM review ≤24h; weekly progress tracker with photos and dates.
- Change control: ECO log for drawing/tolerance updates; approval gates for mold modifications.
8) Risks & Mitigation
- Drawing changes / tolerance disputes → upfront DfM + GD&T review; written FAIR criteria.
- Tooling ownership → contract clause naming owner; custody & storage terms; pull-out rights.
- Finish consistency → master samples, ΔE tracking for colored/anodized parts; fixed bath parameters.
9) Ideal Customers
- MRO/equipment maintenance, engineering contractors, and niche equipment brands needing reliable build-to-print execution with export-grade documentation.
